Numb chin syndrome (NCS)은 드문 신경병증으로 이신경이 지배하는 구강안면 영역의 감각둔화를 특징으로 한다. 이러한 신경병증은 비록 드물지만 악성종양과의 관련성 때문에 임상적으로 중요한 의의를 지닌다. 심지어 이러한 구강안면의 증상이 악성종양의 첫 번째 증상으로 나타나는 경우도 있기 때문에 악성종양의 조기발견을 위해서 치과의사의 특별한 관심이 요구된다. 따라서 특별한 원인 없이 이부의 감각마비를 호소하는 경우에는 진단되지 않은 악성종양의 존재 가능성을 염두에 두어야 하며, 이에 대한 조사가 필요하다. 저자들은 구강안면부에서 갑자기 발생한 찌르는 것 같은 통증과 하악 이부 부위의 감각마비를 주소로 경북대학교병원 구강내과에 내원한 환자가 미만성 큰 B-세포 림프종으로 진단된 사례를 보고하는 바이며, 이를 통해서 NCS 진단의 중요성을 강조하고자 한다.

Numb chin 증후군은 악성질환의 진행과 재발의 소견인 경우 외에도 암의 최초 증상으로 발현하기도 하며, 진단 후 대개 나쁜 경과와 예후를 보이는 것으로 알려져 있다. 저자들은 numb chin 증후군으로 발현한 비소세포폐암 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Numb chin syndrome, or mental neuropathy is a rare sensory neuropathy characterized by abnormal sensation such as hypoesthesia, paresthesia, or dysesthesia in the chin and lower lip innervated by the mental nerve. Sensory neuropathy of mental nerve is somewhat familiar to dentists because it can occur following nerve damage by trauma or dental treatment such as implant surgery or third molar extraction. It can also result from dental causes including abscess or osteomyelitis. However, it can be the first sign of the systemic disease or malignancy if it is not related to dental causes. In this study, we present the case of a patient who present with hypoesthesia and pain in chin area without other symptoms and is later diagnosed with diffuse large B-cell lymphoma.

The purpose of this study is to report a rare case of mandibular adenocarcinoma that was diagnosed due to metastasis from the prostate. Numb chin syndrome (NCS), which was associated with this case, is also discussed. Computed tomography (CT) and an intraoral incisional biopsy of the left mandibular area were performed. Urology consultation, hormone therapy, chemotherapy and follow-up radiographic images were administered. Histological examination of the incised specimen revealed moderately differentiated adenocarcinoma. The Gleason score was 8 (primary 4/secondary 4). Immunohistochemical features and radiographic results confirmed the diagnosis of metastasis from prostate adenocarcinoma, moderately differentiated. The patient's prostate-specific antigen (PSA) level was very high. After hormone treatment, the patient's PSA levels dropped gradually. Seventeen months later, in May 2015, the PSA level was elevated. The 18-month follow-up CT image indicated that the patient's condition was aggravated. Docetaxel chemotherapy was started in June 2015 (18 months later), and the sixth cycle of the therapy is in progress. Oral metastases that originate from prostate adenocarcinoma are rare and can induce various periosteal reactions. Hormone therapy, chemotherapy and close follow-up could be additional, appropriate treatment, and were applied in this case. Finally, NCS is a valuable indicator of metastatic disease in the mandible.
